Seems like a scam. General noise in the background, a pause, then they hang up.

Caller: Greenpeace

Answered, they introduced themselves as an employee from Greenpeace. They’ll manipulate you into donating money.

I called back number 0435 374 336 reached voice mail but did not say for what company.

Caller: Charity on behalf of Greenpeace

Fundraising for Greenpeace. Legit company. Greenpeace has my number in their database because I donate every now and again

Called and asked for me by name but then hung up. I could hear other talking in background like a telemarketing Center

unknown telemarketer

Caller: A leading charity

Missed the call and when I returned it there was a nice message saying thank you for your support.
